Caulking and re-caulking

Dolphin Pool Services, LLC highly recommends caulking the perimeter of your pool (where the coping meets the decking). This is the single most important step you can take in protecting your tile, coping, and decking from the effects of water damage.

If this joint is not properly caulked, water will enter behind the coping, which during the winter months will freeze and expand causing expensive damage to the coping, tiles, beam, and/or decking. Additionally, when water enters this joint, it slowly erodes the dirt from beneath the decking, causing it to drop.

An uneven surface at the perimeter of the pool can be dangerous. Caulking this joint not only protects the tile, coping, and decking from water damage, it provides a nice transition from the decking to the coping. The caulk will prevent dirt and debris from accumulating at the pools’ edge, making it easier to keep the deck and pool clean.
